Weather of Arabia - Record-breaking forest fires, historical floods, heat waves and severe droughts have made headlines in recent months. This raised many questions about the relationship of these extreme events to climate change, and if humans are really responsible for what is happening in the world? A recent report prepared by hundreds of climate experts answers these questions.
Report of the Intergovernmental Panel on Climate Change (IPCC)
On Monday (9 August), the United Nations' Intergovernmental Panel on Climate Change (IPCC) released the first batch of the Sixth Assessment Report of the Intergovernmental Panel on Climate Change at a virtual press event.
In the report, the authors review more than 14,000 studies that document evidence of climate change, record the impact of human activities on global warming, and make model predictions for our future if we fail to reduce carbon dioxide (CO2) and other greenhouse gas emissions that drive climate change today. .
The Intergovernmental Panel on Climate Change, with the agreement of all 195 member states, has agreed that human activity is causing climate change, the most powerful statement ever made by the IPCC.
This report examines the scientific evidence on how the Earth's climate is changing and how human activity is driving that change, and summarizes the findings for global leaders and policy makers. Reports from two additional working groups will be delivered by 2022; These reports will address climate vulnerability, impacts, and adaptation to societies around the world, and potential mitigation strategies, according to the Intergovernmental Panel on Climate Change.
Human activities cause global warming and extreme phenomena
More than 200 scientists authored and edited the new report, and they found that human activity, primarily the production of carbon dioxide in the atmosphere from burning fossil fuels, has warmed the Earth at a rate not seen in the past 2,000 years.
Because of climate change, human societies everywhere on Earth are affected by extreme weather events that are longer, more intense and more frequent.
If current warming continues, the Earth will exceed (1.5)°C of warming and reach (2)°C by 2050, which will increase the intensity of extreme weather events.
As stated in the report: Under all of the future emissions scenarios considered in the report, "surface temperatures will continue to rise until at least mid-century."
"With each additional increase in global warming, changes in extremes continue to increase," the authors wrote. For example, extreme heat waves that used to happen once every decade now occur about three times in 10 years. With only a 0.9 F (0.5 C) increase in average global temperatures, these heat waves will occur four times each decade, resulting in
